I am 100% pro-homebirth, but just to be fair. I did pretty much exactly what briee did. I was 27, worked out including pushups and situps right to the end. Gained 35 pounds on a tall frame (5'8") , ate very healthy mostly vegetarian food, vitamins and supplements up the wazoo. Avoided prenatal care (did it myself) for awhile, finally went in for HCT and confirmation the last three months. Told the physician I was doing it at home, even though it was illegal. He told me I was so healthy I could have a baby on top of a flagpole. I had a veterinarian friend prepare a suturing kit in case I needed it, a midwife and the baby's father helping me. I had an effortless pregnancy with no discomfort, no vomiting. The only difference between me and briee that I can tell is that this was my first and only baby, not my fifth.
Anyway, as you know from my first post, I had to go to the hospital after 7 1/2 hrs of pushing, where I was greeted by rudeness and lectures and intrusive annoying behavior, but I had to put up with it, because the baby was not coming out without that vacuum extractor. (There was also the worst winter weather in the history of Virginia Beach, but that was no problem to us experienced winter drivers.)
They poked her with razors for a useless PKU test, squirted stinging compound in her eyes, suctioned her face, cut the cord too soon, took her away to a nursery, as I had not "planned ahead" with them to room with her. I felt very bad, very worried about her being traumatized by all this. I left the hospital the next morning against medical advice, then, the biggest humiliation of all, I had to be readmitted late the next day with a hemmorhage. I waited and waited because I didn't want to go back there, but otherwise I truly would have bled to death. They had to transfuse me with 7 units of blood. The human body contains 13. So, basically, I had to eat crow twice.
My advice to you is homebirth is wonderful, but have a back up.
